It is also conceivable that at least one sensor is designed in the manner of a film or in the form of a surface, in particular the elongate extension being designed to be significantly larger than the width of the corresponding sensor. As already mentioned, the sensor can be arranged on the motor vehicle in the bumper area or in the door sill area or the lower door area of the side doors. For this purpose, the carrier body from the modular unit according to the invention can be used. It is also conceivable that this sensor extends over the entire width or only a partial area of the width of the bumper or door sill.
- Attaching a sensor in or on the movable part also offers the possibility that the movable part can follow the object in the detection area in that a drive for the movable part is controlled by the sensor device.
- the side door is automatically opened by, for example, a hand or foot (the object) of the operator, in which he only tries to remove the hand from the detection range of the sensor, the sensor detects this movement and instructs the drive, the moving part to follow the object so that it remains in the detection range of the sensor.
- the detection area of the sensors should not protrude into the pivoting area of the movable flap, since this can lead to collisions with the object to be detected. Unless the corresponding sensor is used to make the moving part follow the object, as previously described.
- the sensor device initially carries out a reference measurement with at least one sensor in order to initially detect interfering influences such as weather, obstacles or the like.
- This reference measured value can be stored as a reference value in the electrical unit, in particular in the control unit.
- the sensor can then record a detection of an object in the detection area by measurement. In this way, malfunctions in the operation of the movable part can be reliably avoided. So it is e.g. B. conceivable that the sensor device carries out the mentioned reference measurement during or shortly after the parking process, for example to detect objects in the detection area, which could later lead to measurement errors when the movable flap is actuated as desired.
- This reference measurement can also be used to establish threshold values in the subsequent measurement.
- the sensor device on or off via an additional switch in the vehicle.
- the activation of the sensor device can also be controlled by the vehicle electronics, e.g. B. via the steering lock or the starter switch or a switch on the gear lever or the like.
- a sensor can be equipped with a terminal resistor which is arranged at the end of the sensor electrode. A comparison measurement can thus be used to determine whether the resistance can still be achieved in terms of measurement technology or not. If the terminal resistance is no longer detected, it can be assumed that there is a defect or break in the sensor at some point. B. detected as an error by the control unit and can be further reported to the motor vehicle electronics.
- the sensor element can be loop-shaped or U-shaped so that the input connection and the output connection of the sensor element can be arranged next to one another.
- At least one sensor is equipped with a shielding element.
- This shielding element can be partially wrapped around the sensor as a shielding film in order to define the detection area of the sensor more precisely.
- the detection area of the sensor is then geometrically predetermined at the exposed areas of the sensor that are not enveloped or covered by the shielding film.
- a sensor designed over the entire width of a motor vehicle can only be aimed at the corner areas of the motor vehicle (transition from the rear area to the side area) through the shielding element.
- a so-called active shield is used for one or each sensor in order to direct the detection area forward away from the active shield. The respective sensor is thus arranged between its detection area and its active shield.
- the respective sensor can be partially or entirely plastic or rubber encased with the shielding element and / or the active shield.
- the enclosure of the sensor can for example by a spray or Continuous casting process take place.
- the corresponding sensor with its shielding element and / or its active shield forms an inseparable component.
- the sensor can also be arranged separately from its shielding element and / or its active shield.
- the sensor can also be attached directly or indirectly to the vehicle or the carrier part of the module unit by a mat or a net, the sensor being completely or partially embedded in the mat or the net.
- the mat or the net can then in turn be fastened indirectly via further holding elements, in particular locking elements or clips, as described.
- An additional connection can be made in the area of the clips for improved sensing.
- a first sensor with a first horizontal detection area and at least one second sensor with a second vertical detection area are provided on the motor vehicle in order not only to detect the entry of the object into the detection area of a sensor, but also also the corresponding movement of the object.
- At least one capacitive coupling of a sensor can be changed. It is also conceivable that the capacitive coupling of the further sensors is also designed to be changeable or that this takes place only after a first sensor has been changed.
- the capacitive change can also be regulated via a threshold value, so that, for. B. the first sensor triggers but the second sensor detects that the object has already entered its detection area but is not yet completely present in it. The actuation of the movable part can thus also be controlled in a targeted manner via only partial entry of the object into the detection area of a sensor.
- an access authorization system and / or a security system is only activated when at least one sensor of the sensor device perceives an object in its detection area.
- the access authorization system or the security system can also only be activated when it is ensured that this object actually wants access to the vehicle. This can take place, for example, via the successful detection of a movement sequence of the object or in which two or more sensors detect the object in the detection area. It is therefore also conceivable that the access authorization system and / or the security system are only activated when the measured value of a sensor falls or will fall below a predetermined threshold value.
- Access to the vehicle is usually only released when the access authorization system and / or the security system with a mobile ID transmitter has carried out a successful security query for the access code.
- this query can be made dependent on the measurement result of the sensor device according to the invention, as described above.
- At least one sensor of the sensor device according to the invention serves as an antenna or as an additional antenna for the access authorization system and / or the security system.
- the query of the access authorization system does not have to serve to activate the sensor device according to the invention. Rather, the sensor device can also serve to wake up the access authorization system and / or the security system.
- the additional query of the ID transmitter merely represents a further improvement in security in order to prevent unauthorized opening of the movable part on the motor vehicle.
- An actuation of the camera device in particular the rear camera device, can also be controlled or activated via the sensor device
- the sensor device For example, to avoid mechanical collisions of the vehicle or even only the moving part with an environment during the opening process.
- other technical means for the aforementioned camera are also provided in order to prevent the movable part from colliding with an obstacle or object when it is opened or closed.
- This can also be, for example, a further proximity sensor, a radar system or an ultrasonic sensor or the like. This ensures that the opening or closing process of the movable part takes place - for example only after possible authentication - when it is ensured that there is no object or obstacle in the movement area of the movable part. This can be particularly important in low garages.
- the sensor device according to the invention can also be used to detect depressions and elevations in the detection area of its sensors in order to avoid collisions of the vehicle. The measurement results of the sensors can e.g. B. issued as warnings in the vehicle to the occupants.
- At least one sensor of the sensor device is used to determine whether an object, in particular a person, is located in the range of motion of the movable part. Only when the sensor ensures that no object is detected can the control of the movable part by the electronics unit, in particular the control unit, be released in order to operate the movable part. The risk of trapping can be effectively reduced here.
- the other vehicle-internal sensor systems such as the parking system, the distance warning system or the like, can also be used to determine that a person at risk is outside the danger area of the moving part.
- a sensor of the sensor device can be arranged on the vehicle, in particular on the inside of the bumper or the movable part or on the door sill area, by means of holding elements.
- the holding elements can themselves be designed as clips or locking elements.
- the clips themselves can also be designed so that they can be glued to, for. B. to hold the sensor cohesively.
- Form-fitting loops or retaining means can also be provided on the clips for fastening the sensor.
- at least one sensor can be connected to the module unit according to the invention via the carrier body. It is also conceivable that a separate carrier body is present for each sensor in order to form the module unit. Of course, several sensors can also be arranged next to one another, parallel or one behind the other on a carrier body. It is also conceivable that at least one sensor element is arranged outside of the module unit, whereas another sensor is provided on the carrier element of the module unit.
- At least one sensor can be arranged in a meander shape or in a loop or loop shape in order to form its detection area.
- This configuration of the sensor is particularly important if the sensor should not only detect whether an object is completely in the detection area or not, but if the sensor should also detect whether the object has penetrated its detection area entirely or partially.
- This configuration of the sensor is therefore particularly suitable when working with threshold values in the measurement.
- several sensors of the sensor device according to the invention can also be designed in this way.
- the sensor device according to the invention additionally supports a parking system or a driving guidance system or even for short distances, i.e. H. completely replaced under 2 m.
- the measurement signals detected at the sensor device according to the invention can thus also be used to support the driving safety of the motor vehicle, in particular when parking or at the lowest speeds.
- a sensor is additionally equipped with a heating element or a corresponding heating element is arranged in the vicinity of a sensor in order to allow water to evaporate as quickly as possible in the area of the sensor through the action of additional heat.
- This heating element can also be used to thaw frozen water that has frozen onto the sensor or in the immediate vicinity. This allows the measurement accuracy to be increased significantly, since water in particular causes great metrological interference with a capacitive sensor.
- the heating element is temporarily switched on and off by the electrical unit, depending on the weather is switched off in order to regularly ensure that the direct environment of the respective sensor is designed to be water-free. It should also be mentioned that it is conceivable to use the sensor itself or e.g. B.
- the control unit can ensure this by switching on the sensor or the shielding element once as a heating element and using it once as a sensor or shielding element.
- an additional heating element can also be present in order to generate the required heat.
- the heating element with the sensor and possibly the shielding element to a component by z. B. an envelope or insulation can be combined.
- water guide elements are expediently arranged either directly on the sensor, the support body for the module unit or the bumper, the door sill or the like, with the help of which an attempt is made to divert existing water as far as possible from the detection area of the corresponding sensor. This is intended to minimize the previously described disturbances or negative measuring influences on the respective sensor due to the water that may be present.
- the water guide elements themselves can be designed as projections or tear-off edges or as drainage channels or holes. The aim is to prevent a film of water from forming, in particular in the direct detection area of the sensor.
- the water guide elements can, for example, be designed in a wedge shape, whereby a tear-off edge is formed for a watercourse, on which the water droplets then separate from the water guide element.
- the water guide element can also consist only of a tear-off edge which is incorporated into the carrier body or the bumper or the like. Also conceivable are gutters or breakthroughs for diverting or guiding the water away from the sensor, which are arranged on the support body or the vehicle, in particular the bumper, the door sill or the like.
- the invention is also achieved by a method having all of the features of claim 35. Further possible embodiments of the method are proposed in the respective sub-claims.
- a first and a second sensor are provided, the object, in particular the authorized user, performing a conscious action that is detected by the first or second sensor.
- the conscious action can be, for example, bringing the user closer to the first or the second sensor with his arm or hand.
- the module unit only needs one sensor for the corresponding detection of an object, whereby the actuation of the movable part can be activated via the detection.
- a conscious leg or foot movement of the user is detected by the first sensor and a further body movement of the user is detected by the second sensor.
- At least one lighting unit of the motor vehicle has a defined lighting mode during the detection.
- the module unit is arranged on the rear area and / or on the side door area of the motor vehicle, in particular below a sliding side door.
- An opening process of the sliding door can be triggered by a corresponding detection of a person who is in the vicinity of the sliding side door of the motor vehicle.
- This embodiment is particularly useful in vehicles that are designed as utility vehicles, in particular as transporters or small transporters.
- the electrical unit is advantageously connected to at least one third sensor and / or switch that is arranged inside the motor vehicle, in particular that the third sensor and / or switch is arranged in the motor vehicle in such a way that it is placed over the foot and / or knee and / or or and / or elbow and / or shoulder and / or head of the user can be actuated. Furthermore, it is conceivable that by actuating the third sensor or / or switch, an opening movement and / or closing movement of the Side sliding door is triggered. If the user is inside the motor vehicle, it is conceivable to close the sliding door of the motor vehicle by actuating the third sensor and / or switch. A renewed opening of the sliding side door by actuating the third sensor and / or switch can also be triggered.
- the third sensor and / or switch can be designed as a proximity sensor, non-contact sensor or as a tactile pressure switch.
- the third sensor and / or switch for triggering an opening movement and / or closing movement of the sliding side door of the motor vehicle is advantageously arranged in or on the sliding side door.
- An arrangement in or on the door trim, on the vehicle seat or in the floor area or on various decorative elements within the motor vehicle is also conceivable.
- a closing movement of the sliding side door can be triggered by the user activating the third sensor and / or switch located on the inside, for example. It is also conceivable that, when leaving the motor vehicle, the user must first actuate the third sensor and / or switch located inside. Another detection of the sensor of the module unit is then necessary in order to trigger an actual closing process of the sliding side door. Furthermore, it is also conceivable that the internal third sensor can be triggered via a defined movement pattern.
- the third sensor can expediently be deactivated as a function of the operating state of the motor vehicle. This means that when the motor is "running" or activated, the third sensor and / or switch for opening the sliding side door is deactivated. Nevertheless, it can be provided that such a deactivation can in turn be deactivated by the user so that the user can initiate a closing movement and / or opening movement of the sliding side door via the third sensor and / or switch even when the motor is "running".
- an unlocking and / or locking of a further motor vehicle door and / or tailgate and / or fuel filler flap can be triggered by actuating the third sensor.
- the speed of the opening movement and / or closing movement of the sliding door can be changed, in particular the electrical unit controls and / or regulates the speed of the opening movement and / or closing movement of the sliding door.
- the method according to the invention can be designed in such a way that the actual activation of the movable part takes place after a defined time and / or as a function of a defined distance that the user must have from the module unit. It can be provided here that a defined time is specified which triggers the opening of the movable part with a time delay after a positive detection and / or after a positive authentication process. Due to the construction of the motor vehicle, in particular of the movable part, it can also be advantageous that the movable part is only opened when the user is at a defined distance from the movable part. This means that the necessary distance from the user is determined via the sensor device according to the invention, which is located in the module unit. In one possible embodiment, it may be necessary for the user to first move away from the movable part so that an actuation of the movable part is triggered.
- the module unit is designed with its own lighting unit, which communicates the necessary distance to the user according to its lighting mode. If the user is still too close to the motor vehicle, the lighting unit can, for example, use a first color to signal corresponding information to the user.

- the method according to the invention offers the possibility that the user can operate the ID transmitter at a greater distance from the motor vehicle, so that initially the Authentication process is triggered. Only when the user is in the vicinity of the motor vehicle, in particular the module unit, does a corresponding detection take place via the sensor device in order to activate the actuation of the movable part. This means that the authentication process can precede the detection process for actuating the movable part.
- the sensor device can already be activated after positive authentication.
- the movable part is actuated as a function of a speed signal. This means that actuation of the movable part is only possible when the motor vehicle is stationary and not moving.
- a third sensor is provided, the flap opening via a positive detection via the first and the second sensor, a pane arranged on the flap opening via a positive detection via the first and the third sensor and via a positive detection via the second and third sensor, the flap closes.

- the feet 51 are in the present Fig. 17 however, not attached to the support body 12, so that additional holding elements 50 are used, which are also attached to the support body 12, in particular an upper cross member 12.1.
- the two holding elements 50 are arranged in the upper rear area on the left and right sides of the housing of the electrical unit 13. These holding elements 50 are, for example, materially connected to the housing in order to enable a mechanically secure hold.

- a first cross member 12.1 conical or ramp-shaped projections can be provided, which interact positively with the counter-holding elements 50 ′ designed as bores on the first cross member 12.1. Consequently the electrical unit 13 is securely fastened to the support body 12 or the bumper or the door sill or the like, directly or indirectly, on the vehicle 2, even in the event of strong mechanical influences.

- the feet 51 in the Figure 17 can themselves consist of an elastic material in order to absorb mechanical impacts. It is also conceivable that the electrical unit 13 is connected to the support body 12 or the vehicle 2 in a form-fitting and / or force-fitting and / or material fit only via the feet 51.
- the feet 51 are arranged in U-shaped buffers 52 in order to enable, on the one hand, a form-fitting attachment and, on the other hand, a shock-absorbing mounting of the electronic unit 13 on the vehicle 2 or the carrier body 12.

- a first water guide element 54 in the form of a wedge-shaped element is provided above the first sensor 21 on the outside of the support body 12 or on the bumper of the motor vehicle 2. If the water 55 (see arrow 57) runs along the outside, that is the side facing away from the sensors 21 and 22, it reaches the first water element 54 under the influence of gravity. The water flows due to the existing forces of adhesion 55 along the ramp-shaped water guide element 54 and detaches itself from the support body 12 or the bumper, door sill or the like at the lower tearing edge of the water guide element 54. The water 55 then drips from this tear-off edge onto the floor so that it is reliably prevented from flowing further along the outside and reaching the detection area 5 of the first sensor 21.

- the lower edge of the projection-like water guide element 54 serves as a tear-off edge for the water droplets 55 flowing along it.
- a triangular water guide element 54 is provided on the outer side of the carrier body 12.
- the two inner and outer water guide elements 54 for the first sensor 21 are arranged approximately at the same height on the carrier body 12. With this geometric arrangement, however, it is important that the water flowing away on the surface of the carrier body 12 is torn off in front of the detection area 5.
- a bore, opening or elongated hole or the like is provided in the carrier body 12 so that the water 55 that has accumulated within the carrier body 12 can escape.
- This water guide element 54 can also be arranged on the left and right of the second sensor 22 in order to prevent the water droplets 54 present in the detection area 6 of the second sensor 22 from flowing away.
- FIG. 22 For clarification is in the Figure 22 a three-dimensional view of two elongated water guide elements 54 under the sensor 22 is shown. As already mentioned, it is also expedient to place these slot-like water guide elements 54 on the left and right next to the corresponding sensor 21, 22 to be arranged, whereby an attachment of the corresponding sensor 21, 22 is also facilitated.

Description
Die Erfindung bezieht sich u. a. auf eine Moduleinheit mit einer Sensoreinrichtung für eine Betätigung eines beweglichen Teils, insbesondere einer Klappe eines Kraftfahrzeugs, mit einem Trägerkörper, an dem die Sensoreinrichtung mit wenigstens einem Sensor angeordnet ist, um eine Detektion eines Objektes in wenigstens einem an das Kraftfahrzeug angrenzenden Detektionsbereich zu ermöglichen, sodass über die Detektion die Betätigung des beweglichen Teils aktivierbar ist. Die Betätigung erfolgt vorzugsweise berührungslos. Die Erfindung ist aber auch nur auf eine derartige Sensoreinrichtung sowie auf ein Betätigungsverfahren gerichtet.The invention relates inter alia. to a module unit with a sensor device for actuating a movable part, in particular a flap of a motor vehicle, with a carrier body on which the sensor device with at least one sensor is arranged in order to enable detection of an object in at least one detection area adjoining the motor vehicle, so that the actuation of the movable part can be activated via the detection. The actuation is preferably non-contact. However, the invention is also only directed to such a sensor device and to an actuation method.
Zur berührungslosen Betätigung von beweglichen Teilen eines Kraftfahrzeugs sind Sensoreinrichtungen bekannt, die das Vorhandensein und insbesondere die Bewegung einer Person sensieren, um darin den Wunsch zur Öffnung des beweglichen Teils des Kraftfahrzeugs zu erkennen. Das bewegliche Teil des Kraftfahrzeugs kann eine Klappe und insbesondere eine Heckklappe oder eine Seitentür oder Motorhaube des Kraftfahrzeugs betreffen, wobei auch bewegliche Fensterelemente bekannt sind, wie etwa eine in einer Heckklappe bewegbare Heckscheibe, die dann durch eine gattungsbildende Sensoreinrichtung vorteilhaft geöffnet oder geschlossen werden kann, wenn eine manuelle Betätigung der Heckklappe nicht oder nur erschwert möglich ist. Im Folgenden wird das bewegliche Teil vereinfachend als Klappe bezeichnet.For the contactless actuation of moving parts of a motor vehicle, sensor devices are known which sense the presence and in particular the movement of a person in order to recognize therein the desire to open the moving part of the motor vehicle. The moving part of the Motor vehicle can relate to a flap and in particular a tailgate or a side door or bonnet of the motor vehicle, movable window elements are also known, such as a rear window movable in a tailgate, which can then advantageously be opened or closed by a generic sensor device when manual actuation the tailgate is not possible or only with difficulty. In the following, the movable part is referred to for the sake of simplicity as a flap.
Das durch die Sensoreinrichtung detektierte Objekt kann eine Person sein, die sich dem Kraftfahrzeug in der Absicht nähert, die Heckklappe zu öffnen. Die Betätigung der Heckklappe beschreibt dabei sowohl einen Öffnungsvorgang, beispielsweise wenn die Person einen Gegenstand beidhändig in den Kofferraum einlegen möchte, oder die Betätigung der Heckklappe betrifft einen Schließvorgang der Heckklappe, wenn die Person beidhändig einen Gegenstand aus dem Kofferraum entnommen hat, um anschließend die Heckklappe zu schließen.The object detected by the sensor device can be a person who approaches the motor vehicle with the intention of opening the tailgate. The operation of the tailgate describes both an opening process, for example when the person wants to insert an object into the trunk with both hands, or the operation of the tailgate relates to a closing operation of the tailgate when the person has removed an object from the trunk with both hands in order to then open the tailgate close.
Die bekannte Sensoreinrichtung umfasst dabei wenigstens einen Sensor, der über einen Trägerkörper am Kraftfahrzeug angeordnet ist. Die Sensoren zur Heckklappenbetätigung sind gewöhnlich innenseitig im Stoßfänger angebracht, so dass der Trägerkörper durch den Stoßfänger selbst gebildet ist. Dabei ist bekannt, die Sensoren innenseitig auf der Oberfläche des Stoßfängers aufzukleben oder zu laminieren, wobei die Sensoren als kapazitiv wirkende Elektroden drahtartig oder folienartig ausgebildet sind. Dabei werden die Drähte oder Folien der durch Elektroden gebildeten Sensoren wenigstens über einen Teil oder bevorzugt über der gesamten Breite des Stoßfängers des Kraftfahrzeugs angebracht. Folglich ist eine Betätigung der Heckklappe des Kraftfahrzeugs aus verschiedenen Bereichen in der näheren Umgebung des Hecks des Kraftfahrzeugs möglich. Damit sind die Sensoren Bestandteil des hinteren Stoßfängers, die innenseitig im Stoßfänger aufgeklebt oder mit Befestigungsmitteln am Stoßfänger befestigt sind. Insbesondere ist bekannt, die Sensoren bereits im Kunststoff-Spritzgussprozess zur Herstellung des Stoßfängers einzusetzen, um ein einteiliges Bauteil mit umspritzten Sensoren zu erhalten.The known sensor device comprises at least one sensor which is arranged on the motor vehicle via a carrier body. The sensors for actuating the tailgate are usually mounted on the inside of the bumper, so that the support body is formed by the bumper itself. It is known to glue or laminate the sensors on the inside of the surface of the bumper, the sensors being designed as capacitive electrodes in the form of wires or foils. The wires or foils of the sensors formed by electrodes are attached over at least part of or preferably over the entire width of the bumper of the motor vehicle. It is consequently possible to actuate the tailgate of the motor vehicle from different areas in the vicinity of the rear of the motor vehicle. This means that the sensors are part of the rear bumper and are glued onto the inside of the bumper or attached to the bumper with fasteners. In particular, it is known to use the sensors in the plastic injection molding process for the production of the bumper in order to obtain a one-piece component with overmolded sensors.
Es hat sich nachteiligerweise gezeigt, dass der Montageaufwand derartiger Sensoreinrichtungen groß ist.It has been shown, disadvantageously, that the assembly effort of such sensor devices is great.
Die Aufgabe der vorliegenden Erfindung ist es, eine Moduleinheit mit einer oben beschriebenen Sensoreinrichtung zu schaffen, die auf einfache und montagefreundliche Weise am Kraftfahrzeug befestigbar ist.The object of the present invention is to create a module unit with a sensor device described above, which can be attached to the motor vehicle in a simple and easy-to-assemble manner.
Diese Aufgabe wird durch eine Moduleinheit mit allen Merkmalen des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by a modular unit with all the features of
Ein wesentlicher Kern der vorliegenden Erfindung ist es, dass ein einzeln handhabbares Modul geschaffen wird, welches auf einfache Weise am Kraftfahrzeug, insbesondere am Heckbereich befestigt werden kann. Hierbei sind vorzugsweise entsprechende Befestigungselemente an der Moduleinheit vorgesehen, mit denen die Moduleinheit am Kraftfahrzeug zuverlässig angeordnet werden kann. Hierbei kann die Moduleinheit form-, kraft- und/oder stoffschlüssig mit einem kraftfahrzeugseitigen Teil befestigt werden. Beispielsweise ist es denkbar, dass die Moduleinheit an einem Kraftfahrzeugteil verrastet, angeklipst oder eingeschoben wird. Eine Klebverbindung ist ebenfalls denkbar. Die Moduleinheit, insbesondere der Trägerkörper, bestehen zumindest teilweise aus Kunststoff. Die Sensoren können kapazitive, optische oder Berührungssensoren, insbesondere Piezosensoren, sein.An essential core of the present invention is that an individually manageable module is created which can be attached in a simple manner to the motor vehicle, in particular to the rear area. In this case, corresponding fastening elements are preferably provided on the module unit, with which the module unit can be reliably arranged on the motor vehicle. Here, the module unit can be attached to a part on the motor vehicle side in a form-fitting, force-fitting and / or material fit.

The module unit, in particular the carrier body, consist at least partially of plastic. The sensors can be capacitive, optical or touch sensors, in particular piezo sensors.
Hierbei ist es wesentlich, dass eine mit der Sensoreinrichtung verbundene Elektrikeinheit, insbesondere Steuereinheit, am Trägerkörper angeordnet ist. Diese Elektrikeinheit gibt die von den Sensoren übermittelten Signale einer Hauptelektrikeinheit weiter, die kraftfahrzeugseitig angeordnet ist. In einer möglichen Ausführungsform der Erfindung kann die Elektrikeinheit kabellos Signale der kraftfahrzeugseitigen Hauptelektrikeinheit übermitteln. In einer denkbaren Ausführungsform der Erfindung kann die Elektrikeinheit der Moduleinheit gleichzeitig als Hauptelektrikeinheit des Kraftfahrzeuges wirken. Die Sensoreinrichtung kann in einer möglichen Ausführungsform in der Elektrikeinheit integriert sein.It is essential here that an electrical unit connected to the sensor device, in particular a control unit, is arranged on the carrier body. This electrical unit forwards the signals transmitted by the sensors to a main electrical unit which is arranged on the motor vehicle side. In one possible embodiment of the invention, the electrical unit can wirelessly transmit signals from the main electrical unit on the motor vehicle. In a conceivable embodiment of the invention, the electrical unit of the module unit can simultaneously act as the main electrical unit of the motor vehicle. In one possible embodiment, the sensor device can be integrated in the electrical unit.
Vorteilhafterweise weist die Sensoreinrichtung mindestens einen ersten und einen zweiten Sensor auf, wobei die Sensoren unterschiedliche Detektionsbereiche aufweisen, wobei insbesondere die unterschiedlichen Detektionsbereiche unterschiedlich groß sind. Die Moduleinheit kann derart ausgeführt sein, dass mindestens ein Sensor eine seitliche Anordnung am Kraftfahrzeug aufweist, das bedeutet nicht an der Heckpartie des Kraftfahrzeuges angeordnet ist, sondern an einem Seitenbereich des Kraftfahrzeuges.The sensor device advantageously has at least a first and a second sensor, the sensors having different detection areas, in particular the different detection areas being of different sizes. The module unit can be designed in such a way that at least one sensor has a lateral Has arrangement on the motor vehicle, that is, is not arranged on the rear of the motor vehicle, but on a side area of the motor vehicle.
Ebenfalls ist es denkbar, dass der Trägerkörper am Kraftfahrzeug formschlüssig, kraftschlüssig und/oder stoffschlüssig befestigbar ist, wobei insbesondere der Trägerkörper über eine Rastverbindung am Kraftfahrzeug befestigbar ist oder am Kraftfahrzeug einschiebbar ist. Das entsprechende kraftfahrzeugseitige Teil, an dem der Trägerkörper angeordnet ist, kann mit entsprechenden Befestigungselementen ausgeführt sein, die mit den Befestigungselementen des Trägerkörpers zur zuverlässigen Fixierung zusammenwirken.It is also conceivable that the support body can be attached to the motor vehicle in a form-fitting, non-positive and / or material fit, wherein in particular the support body can be fastened to the motor vehicle via a latching connection or can be pushed into the motor vehicle. The corresponding part on the motor vehicle side, on which the carrier body is arranged, can be designed with corresponding fastening elements which interact with the fastening elements of the carrier body for reliable fixing.
In einer Variante der Erfindung ist die Moduleinheit am Emblem des Kraftfahrzeuges angeordnet oder weist ein Emblem des Kraftfahrzeuges auf, wobei das Emblem sichtbar am Kraftfahrzeug angeordnet ist.In a variant of the invention, the module unit is arranged on the emblem of the motor vehicle or has an emblem of the motor vehicle, the emblem being visibly arranged on the motor vehicle.
In der Regel weist das Kraftfahrzeug eine schwenkbare Heckklappe auf. Ebenfalls ist es denkbar, dass eine Heckkameravorrichtung als Einparkhilfe am Kraftfahrzeug, insbesondere an der Heckklappe, vorgesehen ist. Hierbei ist es denkbar, dass die Moduleinheit an der Heckklappe und/oder zumindest teilweise an der Heckkameravorrichtung integriert ist. Die Moduleinheit kann einen ersten und einen zweiten Sensor umfassen, die innerhalb der Heckkameravorrichtung angeordnet sind. Ebenfalls ist es möglich, dass die Kamera der Heckkameravorrichtung als ein Sensor der Sensoreinrichtung wirkt, um eine Detektion eines sich in der Nähe des Kraftfahrzeuges befindenden Objektes auszuführen. Gleichzeitig kann die Kamera dieser Heckkameravorrichtung in einer anderen Funktionsweise selbstverständlich als Einparkhilfe dienen.As a rule, the motor vehicle has a pivotable tailgate. It is also conceivable that a rear camera device is provided as a parking aid on the motor vehicle, in particular on the tailgate. It is conceivable here that the module unit is integrated on the tailgate and / or at least partially on the rear camera device. The module unit may comprise a first and a second sensor which are arranged within the rear view camera device. It is also possible for the camera of the rear camera device to act as a sensor of the sensor device in order to detect an object located in the vicinity of the motor vehicle. At the same time, the camera of this rear camera device can of course serve as a parking aid in a different mode of operation.
Vorzugsweise weist der Sensor eine längliche Erstreckung auf, wobei insbesondere der Sensor flexibel ausgeführt ist. Eine der Vorteile einer flexiblen Sensoreinrichtung ist, dass sich hierdurch Vorteile bei der Montage ergeben.The sensor preferably has an elongated extension, the sensor in particular being designed to be flexible. One of the advantages of a flexible sensor device is that it results in advantages during assembly.
Die Sensoreinrichtung und/oder die Elektrikeinheit können form-, kraft- und/oder stoffschlüssig am Trägerkörper befestigt sein. Alternativ können die Sensoreinrichtung und/oder die Elektrikeinheit im Trägerkörper integriert sein, insbesondere die Sensoreinrichtung und/oder die Elektrikeinheit mit dem Trägerkörper ein monolithisches Bauteil bilden. Um eine zuverlässige Detektion eines Objektes zu gewährleisten, weist die Sensoreinrichtung eine Erstreckung auf, die in Breitenrichtung des Kraftfahrzeuges verläuft, wobei insbesondere die Sensoren zueinander im Wesentlichen parallel verlaufen.The sensor device and / or the electrical unit can be attached to the carrier body in a form-fitting, force-fitting and / or cohesive manner. Alternatively, the sensor device and / or the electrical unit can be integrated in the carrier body, in particular the The sensor device and / or the electrical unit form a monolithic component with the carrier body. In order to ensure reliable detection of an object, the sensor device has an extension that extends in the width direction of the motor vehicle, with the sensors in particular extending essentially parallel to one another.
Eine die Erfindung erweiternde Maßnahme kann vorsehen, dass die Elektrikeinheit mit mindestens einem weiteren dritten Sensor, der kraftfahrzeugseitig angeordnet ist, in Datenkommunikation steht, insbesondere verbunden ist. Hierbei kann der dritte Sensor im Reifen, an der Heckkameravorrichtung, an einer Nummernschildbeleuchtungseinheit, an einer Zierleiste, an einem Stoßfänger, an einem Schließzylinder einer Verriegelungseinheit, in einer Verriegelungseinheit zur Sperrung der Lenkung, in einer Scheibenwischeranordnung, in einer Heckleuchte, in einem Griff des Kraftfahrzeuges angeordnet sein. Der dritte Sensor kann beispielsweise ein Wärmesensor, ein Abstandssensor, ein Sprachsensor, ein Bildsensor, insbesondere zur Gesichtsfelderkennung sein.A measure expanding the invention can provide that the electrical unit is in data communication, in particular connected, with at least one further third sensor which is arranged on the motor vehicle side. Here, the third sensor in the tire, on the rear camera device, on a license plate lighting unit, on a trim strip, on a bumper, on a lock cylinder of a locking unit, in a locking unit for locking the steering, in a windshield wiper arrangement, in a rear light, in a handle of the Be arranged motor vehicle. The third sensor can be, for example, a heat sensor, a distance sensor, a voice sensor, an image sensor, in particular for visual field recognition.
Um die Montagefreundlichkeit weiter zu erhöhen, können Positionierungsmittel vorgesehen sein, um eine eindeutige Befestigung des Trägerkörpers am Kraftfahrzeug zu gewährleisten. Die Positionsmittel können beispielsweise am Trägerkörper angeformte Aussparungen oder Einsparungen sein, die nur in einer Position am zu befestigenden Bauteil des Kraftfahrzeuges angeordnet werden können. Somit wird gewährleistet, dass die am Trägerkörper angeordneten Sensoren auch die gewünschte Position zur zuverlässigen Detektion eines Objektes im Bereich des Kraftfahrzeuges aufweisen.In order to further increase the ease of assembly, positioning means can be provided in order to ensure that the carrier body is clearly attached to the motor vehicle. The positioning means can, for example, be cutouts or cutouts formed on the carrier body, which can only be arranged in one position on the component of the motor vehicle to be fastened. This ensures that the sensors arranged on the carrier body also have the desired position for reliable detection of an object in the area of the motor vehicle.
Vorzugsweise weist die Elektrikeinheit eine Platine auf, auf der die Sensoren angeordnet sind, wobei insbesondere die Platine mit den Sensoren innerhalb einer Vergussmasse integriert sind. Alternativ kann die Moduleinheit auch ein Kunststoffgehäuse aufweisen, innerhalb der sich die Sensoreinrichtung einschließlich der Elektrikeinheit befindet. Das Gehäuse kann über entsprechende Befestigungsmittel am Kraftfahrzeug fixiert werden.The electrical unit preferably has a circuit board on which the sensors are arranged, in particular the circuit board with the sensors being integrated within a potting compound. Alternatively, the module unit can also have a plastic housing within which the sensor device including the electrical unit is located. The housing can be fixed to the motor vehicle using suitable fastening means.
In einer möglichen Ausgestaltung der Moduleinheit kann innerhalb des Trägerkörpers mindestens ein Sensor als Teilsensor integriert sein, wobei insbesondere mindestens eine Kontaktstelle des Teilsensors aus dem Trägerkörper herausragt. Das bedeutet, dass ein erster Teilsensor sich innerhalb des Trägerkörpers befindet, wobei ein zweiter Teilsensor auf den Trägerkörper befestigt wird und beide Teilsensoren entsprechend über Kontaktstellen verbunden sind, so dass beide Teilsensoren einen Gesamtsensor bilden.In one possible embodiment of the modular unit, at least one sensor can be integrated as a partial sensor within the carrier body, with in particular at least one contact point of the partial sensor protruding from the carrier body. This means that a first partial sensor is located within the carrier body, with a second partial sensor the support body is attached and both partial sensors are connected accordingly via contact points, so that both partial sensors form an overall sensor.
Vorzugsweise weist der Trägerkörper eine Aufnahme auf, in der sich die Elektrikeinheit sich befindet, insbesondere ein Deckelelement abdichtend die Aufnahme verschließt. Das Deckelelement kann beispielsweise mit einer entsprechenden Dichtung ausgeführt sein, so dass kein Schmutz, Feuchtigkeit etc. in die Aufnahme gelangt und somit die Funktionsfähigkeit der Elektrikeinheit gestört wird.The carrier body preferably has a receptacle in which the electrical unit is located, in particular a cover element sealingly closes the receptacle. The cover element can, for example, be designed with a corresponding seal so that no dirt, moisture, etc. get into the receptacle and thus the functionality of the electrical unit is impaired.
Zweckmäßigerweise weist der Trägerkörper mindestens ein Versteifungselement auf, das insbesondere gleichzeitig der Sensor ist. Das Versteifungselement kann beispielsweise ein Metallstreifen oder Metallplättchen sein, welches den Trägerkörper in seiner Konstruktion verstärkt. In der besonderen Ausgestaltungsform der Erfindung kann dieses Versteifungselement als Elektrode dienen, die somit die Funktion des Sensors übernimmt, um Bestandteil der erfindungsgemäßen Sensoreinrichtung zu sein.The carrier body expediently has at least one stiffening element which, in particular, is at the same time the sensor. The stiffening element can, for example, be a metal strip or metal plate, which reinforces the construction of the support body. In the particular embodiment of the invention, this stiffening element can serve as an electrode, which thus takes over the function of the sensor in order to be part of the sensor device according to the invention.
Vorteilhafterweise ist ein Überprüfungsmodul vorgesehen, das die Funktionsweise der Sensoreinrichtung überprüft. Das Überprüfungsmodul kann sich beispielsweise in der Nähe des jeweiligen Sensors befinden, wobei das Überprüfungsmodul vorzugsweise am Trägerkörper befestigt ist. Selbstverständlich ist es in einer alternativen Ausführungsform ebenfalls denkbar, dass ein derartiges Überprüfungsmodul kraftfahrzeugseitig angeordnet ist und somit von einer größeren Distanz die Überprüfung der Funktionsweise der Sensoreinrichtung durchführt.A checking module is advantageously provided which checks the functionality of the sensor device. The checking module can, for example, be located in the vicinity of the respective sensor, the checking module preferably being attached to the carrier body. Of course, in an alternative embodiment it is also conceivable that such a checking module is arranged on the motor vehicle side and thus carries out the checking of the functionality of the sensor device from a greater distance.
In einer weiteren Ausgestaltung der Moduleinheit kann ein von außen zugänglicher Notschalter vorgesehen sein, der über eine taktile Aktion des Benutzers aktivierbar ist. Falls die Moduleinheit oder die Sensoreinrichtung in ihrer Funktionsweise gestört ist, kann über eine Berührung des Notschalters ebenfalls ein Signal ausgelöst werden, welches eine Betätigung des beweglichen Teils aktivieren kann.In a further embodiment of the modular unit, an externally accessible emergency switch can be provided, which can be activated via a tactile action by the user. If the functionality of the module unit or the sensor device is disturbed, a signal can also be triggered by touching the emergency switch, which signal can activate the moving part.
Die Aktivierung des beweglichen Teils nach einer positiven Detektion durch die Sensoreinrichtung, bedeutet gemäß dieser Erfindung, dass das bewegliche Teil aus seiner geschlossenen Position in seine offene Position und umgekehrt bewegt werden kann. Hierbei ist jedoch zu berücksichtigen, dass erst eine Betätigung des beweglichen Teils, das bedeutet eine Bewegung des beweglichen Teils, in seine Offenposition und/oder Schließposition erst dann erfolgt, wenn zusätzlich eine positive Authentifizierung mit dem Objekt stattgefunden hat. Diese Authentifizierung erfolgt in der Regel über einen ID-Geber, den die berechtigte Person mit sich trägt. Der ID-Geber weist hierbei einen entsprechenden Identifikationscode auf, der fahrzeugseitig zur Authentifizierung überprüft wird. Erst bei einer positiven Authentifizierung erfolgt eine entsprechende Betätigung des beweglichen Teils.The activation of the movable part after a positive detection by the sensor device means, according to this invention, that the movable part can be moved from its closed position into its open position and vice versa. Here, however, it must be taken into account that the movable part is only actuated, that is to say the movable part is moved into its open position and / or closed position, only when a positive authentication with the object has also taken place. This authentication usually takes place via an ID transmitter that the authorized person carries with them. The ID transmitter has a corresponding identification code that is checked by the vehicle for authentication. A corresponding actuation of the movable part takes place only with a positive authentication.
In einer möglichen Ausgestaltung der Erfindung kann die Energieversorgung der Elektrikeinheit induktiv erfolgen. Beispielsweise weist die Elektrikeinheit ein Spulenelement auf, welches mit einem Gegenspulenelement zusammenwirkt und eine entsprechende Energieversorgung der Elektrikeinheit induktiv bereitgestellt werden kann.In one possible embodiment of the invention, the electrical unit can be supplied with energy inductively. For example, the electrical unit has a coil element which interacts with a counter-coil element and a corresponding energy supply for the electrical unit can be provided inductively.
Bei einer möglichen Variante der Erfindung kann eine Leuchteinheit vorgesehen sein, die insbesondere während der Detektion aktiviert ist. Hierbei ist es denkbar, dass die Leuchteinheit über eine definierte Leuchtweise dem Benutzer eine Rückmeldung gibt. Beispielsweise können Blinker oder Heckleuchten als Leuchteinheit dienen, die während oder nach erfolgreicher Detektion und/oder Authentifikation leuchten oder blinken. Ebenfalls kann zusätzlich oder alternativ ein akustisches Signal eine entsprechende Rückmeldung während oder nach erfolgreicher Detektion und/oder Authentifikation dem Benutzer geben.In a possible variant of the invention, a light unit can be provided which is activated in particular during the detection. It is conceivable here that the lighting unit gives the user feedback via a defined lighting method. For example, turn signals or rear lights can serve as a lighting unit that light up or flash during or after successful detection and / or authentication. Additionally or alternatively, an acoustic signal can also give the user a corresponding feedback during or after successful detection and / or authentication.
Eine die Erfindung verbessernde Maßnahme kann vorsehen, dass eine Schwellwertregelung vorgesehen ist, die eine tatsächliche Berührung des Benutzers am beweglichen Teil erkennt. Falls sich der Benutzer unmittelbar am beweglichen Teil anlehnt bzw. dieses Teil berührt, ohne eine tatsächliche Betätigung des beweglichen Teils aktivieren zu wollen, erkennt dieses die Schwellwertregelung, so dass ein Öffnungsvorgang des beweglichen Teils nicht aktiviert wird.A measure improving the invention can provide that a threshold value control is provided which detects an actual touch of the user on the movable part. If the user leans directly against the movable part or touches this part without actually wanting to activate the movable part, the latter recognizes the threshold value control so that an opening process of the movable part is not activated.
Ebenfalls ist es denkbar, dass mindestens ein Sensor zwischen dem Trägerkörper und dem kraftfahrzeugseitigem Bauteil angeordnet ist, wobei insbesondere der Trägerkörper mit einem Profil, das zum kraftfahrzeugseitigen Bauteil gerichtet ist, ausgeführt ist und dem Sensor eine bestimmte Einbaulage bietet, die insbesondere zur Außenseite abgedichtet ist. Ferner ist es denkbar, dass die Elektrikeinheit über Halteelemente form- und/oder kraftschlüssig mittels Gegenhalteelemente am Fahrzeug oder am Trägerkörper der Moduleinheit befestigt werden kann. Diese Halteelemente können als Rastelemente oder Clipselemente oder dergleichen ausgestaltet sein, um somit sicher die Elektrikeinheit, insbesondere die Steuereinheit, an dem Fahrzeug bzw. dem Trägerkörper der Moduleinheit zu befestigen. Hierbei ist es beispielsweise denkbar, dass die Halteelemente an dem Gehäuse der Elektrikeinheit integriert sind, um zum Beispiel mit dem Fahrzeug mechanisch zusammenwirken zu können. Auch ist es denkbar, dass die Halteelemente an dem Fahrzeug, insbesondere dem Stoßfänger, dem Türschweller oder dergleichen bzw. dem Trägerkörper der Moduleinheit integriert sind. Diese Halteelemente arbeiten mit Gegenhalteelemente an dem anderen Element zusammen. Dabei kann die Elektrikeinheit zum Beispiel hängend oder stehend über die Halteelemente mit dem Fahrzeug direkt oder indirekt befestigt werden. Auch ist es denkbar, dass zusätzlich zu den vorgesehenen Halteelementen, Pufferelemente vorgesehen sind, mit denen sich die Elektrikeinheit an dem fahrzeugseitigen Element oder dem Trägerkörper der Moduleinheit abstützt und die einen wesentlichen Teil der Gewichtskraft der Elektrikeinheit aufnehmen. Durch diese Pufferelemente können Toleranzen und Schwingungen, die unweigerlich bei einem Fahrzeug entstehen, abgefedert und/oder gedämpft werden, um die Elektrikeinheit vor mechanischen Einflüssen weitestgehend zu schützen. Ebenfalls kann es vorgesehen sein, dass die Halteelemente mit den Pufferelementen integriert sind, um somit die Elektrikeinheit am Fahrzeug bzw. am Trägerkörper der Moduleinheit zu befestigen. Ferner ist es denkbar, dass auch nur die Pufferelemente genutzt werden, um die Elektrikeinheit zu befestigen, wobei hierbei vorteilhafterweise die Pufferelement formschlüssig mit den entsprechenden Gegenelementen am Fahrzeug oder an dem Trägerkörper zusammen wirken. Sowohl die Halteelemente als auch die Pufferelemente können direkt am Gehäuse angespritzt, angeschweißt, angeklebt, geschraubt oder anderweitig befestigt werden, um somit die Elektrikeinheit sicher am Fahrzeug unterzubringen. Entsprechende Gegenelemente, die zum Beispiel aus einer Bohrung bestehen können, oder ebenfalls aus Rastelementen, können genauso wie die Halteelemente beispielsweise am Stoßfänger, Türschweller bzw. Trägerkörper der Moduleinheit oder dergleichen befestigt werden. Die Halteelemente können zusätzliche Metallclips aufweisen, oder Schraubelemente oder dergleichen, die zur Befestigung der Elektrikeinheit dienen.It is also conceivable that at least one sensor is arranged between the support body and the component on the motor vehicle side, the support body in particular being designed with a profile that is directed towards the component on the motor vehicle side and offering the sensor a specific installation position that is sealed off from the outside in particular . Furthermore, it is conceivable that the electrical unit can be attached to the vehicle or to the carrier body of the module unit in a form-fitting and / or force-fitting manner by means of counter-holding elements. These holding elements can be designed as latching elements or clip elements or the like in order to securely fasten the electrical unit, in particular the control unit, to the vehicle or the carrier body of the module unit. It is conceivable here, for example, that the holding elements are integrated on the housing of the electrical unit in order to be able to interact mechanically with the vehicle, for example. It is also conceivable that the holding elements are integrated on the vehicle, in particular the bumper, the door sill or the like or the carrier body of the module unit. These holding elements work together with counter holding elements on the other element. The electrical unit can, for example, be attached to the vehicle directly or indirectly in a hanging or standing position via the holding elements. It is also conceivable that, in addition to the retaining elements provided, buffer elements are provided with which the electrical unit is supported on the vehicle-side element or the carrier body of the module unit and which absorb a substantial part of the weight of the electrical unit. These buffer elements can be used to cushion and / or dampen tolerances and vibrations that inevitably arise in a vehicle, in order to protect the electrical unit from mechanical influences as far as possible. It can also be provided that the holding elements are integrated with the buffer elements in order to thus fasten the electrical unit to the vehicle or to the carrier body of the module unit. It is also conceivable that only the buffer elements are used to fasten the electrical unit, the buffer elements advantageously interacting with the corresponding counter-elements on the vehicle or on the carrier body. Both the retaining elements and the buffer elements can be injection-molded, welded, glued, screwed or otherwise fastened directly onto the housing in order to safely accommodate the electrical unit on the vehicle. Corresponding counter-elements, which can consist of a bore, for example, or also of latching elements, can be fastened just like the holding elements, for example, to the bumper, door sill or carrier body of the module unit or the like. The holding elements can have additional metal clips, or screw elements or the like, which are used to fasten the electrical unit.
Es ist auch Aufgabe der vorliegenden Erfindung eine Sensoreinrichtung für eine Betätigung eines beweglichen Teils, insbesondere einer Klappe eines Kraftfahrzeuges, bereitzustellen, die eine sichere Handhabung bzw. Betätigung des beweglichen Teils ermöglicht und kostengünstig herstellbar ist.It is also an object of the present invention to provide a sensor device for actuating a movable part, in particular a flap of a motor vehicle, which enables safe handling or actuation of the movable part and which can be manufactured inexpensively.
Die Erfindung umfasst auch eine Sensoreinrichtung für eine Betätigung eines beweglichen Teils, insbesondere einer Klappe eines Kraftfahrzeuges, mit wenigstens einem Sensor, um eine Detektion eines Objektes in wenigstens einem an das Kraftfahrzeug angrenzenden Detektionsbereich zu ermöglichen, so dass über die Detektion die Betätigung des beweglichen Teils aktivierbar ist, wobei der Sensor als kapazitiver Sensor ausgestaltet ist. Hierbei können auch sämtliche technische Merkmale für die Sensoreinrichtung vorgesehen sein, die zur Sensoreinrichtung bei der erfindungsgemäßen Moduleinheit bereits aufgeführt worden sind oder bei der Sensoreinrichtung bei dem erfindungsgemäßen Verfahren offenbart werden. Somit es ist für die erfindungsgemäße Sensoreinrichtung nicht zwingend notwendig, dass diese ebenfalls über einen Trägerkörper zu einer Moduleinheit aufgebaut ist.The invention also includes a sensor device for actuating a movable part, in particular a flap of a motor vehicle, with at least one sensor to enable detection of an object in at least one detection area adjacent to the motor vehicle, so that the actuation of the movable part via the detection can be activated, the sensor being designed as a capacitive sensor. In this case, all the technical features for the sensor device can also be provided that have already been listed for the sensor device in the modular unit according to the invention or are disclosed in the sensor device in the method according to the invention. It is therefore not absolutely necessary for the sensor device according to the invention that it is also built up to form a module unit via a carrier body.
Wie bereits erwähnt, kann zumindest ein Sensor als ein Draht oder einer Leiterfolie ausgestaltet sein, die insbesondere über eine längliche Erstreckung verfügt. Ebenfalls ist es denkbar, dass zumindest ein Sensor folienartig oder flächenförmig ausgebildet ist, wobei insbesondere die längliche Erstreckung deutlich größer ausgestaltet ist als die Breite des entsprechenden Sensors. Wie bereits erwähnt, kann der Sensor am Kraftfahrzeug im Stoßfängerbereich oder im Türschwellerbereich bzw. unterem Türbereich der Seitentüren angeordnet sein. Hierzu kann der Trägerkörper aus der erfindungsgemäßen Moduleinheit genutzt werden. Auch ist es denkbar, dass sich dieser Sensor über die ganze Breite oder nur einem Teilbereich der Breite des Stoßfängers bzw. Türschwellers erstreckt. Auch ist es denkbar, dass mehrere Sensoreinrichtungen bzw. mehrere Moduleinheiten bei einem Kraftfahrzeug eingesetzt werden, um z. B. die Seitentüren, die Kofferraumklappe und/oder den Motorraumdeckel als bewegliches Teil zu betätigen. Hierbei kann zumindest ein Sensor auch direkt an dem beweglichen Teil angeordnet sein. Diese Anordnung ist besonders an den Seitentüren interessant, da hier wenig Platz besteht, um die Sensoreinrichtung an der feststehenden Karosserie des Kraftfahrzeuges anzuordnen.As already mentioned, at least one sensor can be designed as a wire or a conductor foil, which in particular has an elongate extension. It is also conceivable that at least one sensor is designed in the manner of a film or in the form of a surface, in particular the elongate extension being designed to be significantly larger than the width of the corresponding sensor. As already mentioned, the sensor can be arranged on the motor vehicle in the bumper area or in the door sill area or the lower door area of the side doors. For this purpose, the carrier body from the modular unit according to the invention can be used. It is also conceivable that this sensor extends over the entire width or only a partial area of the width of the bumper or door sill. It is also conceivable that several sensor devices or several modular units are used in a motor vehicle in order to e.g. B. to operate the side doors, the trunk lid and / or the engine compartment lid as a moving part. Here, at least one sensor can also be arranged directly on the movable part. This arrangement is of particular interest on the side doors, since there is little space here to arrange the sensor device on the stationary body of the motor vehicle.
Die Anbringung eines Sensors in oder an dem beweglichen Teil weist zusätzlich die Möglichkeit auf, dass das bewegliche Teil dem Objekt im Detektionsbereich folgen kann, in dem ein Antrieb für das bewegliche Teil durch die Sensoreinrichtung gesteuert wird. Somit ist es möglich, dass z. B. die Seitentür durch beispielsweise eine Hand oder ein Fuß (das Objekt) des Bedieners selbstständig geöffnet wird, in dem er nur die Hand versucht aus dem Detektionsbereich des Sensors zu entfernen, wobei der Sensor diese Bewegung erfasst und den Antrieb anweist, das bewegliche Teil dem Objekt zu folgen, damit es in dem Detektionsbereich des Sensors verbleibt.Attaching a sensor in or on the movable part also offers the possibility that the movable part can follow the object in the detection area in that a drive for the movable part is controlled by the sensor device. Thus it is possible that, for. B. the side door is automatically opened by, for example, a hand or foot (the object) of the operator, in which he only tries to remove the hand from the detection range of the sensor, the sensor detects this movement and instructs the drive, the moving part to follow the object so that it remains in the detection range of the sensor.
Um die Handhabung der Sensoreinrichtung zur Betätigung des beweglichen Teils möglichst zu vereinfachen, sollte der Detektionsbereich der Sensoren nicht in den Schwenkbereich der beweglichen Klappe ragen, da es hierbei zu Kollisionen mit dem zu erfassenden Objekt kommen kann. Es sei denn, der entsprechende Sensor dient dazu, das bewegliche Teil dem Objekt folgen zu lassen, wie zuvor beschrieben worden ist.In order to simplify the handling of the sensor device for actuating the movable part as much as possible, the detection area of the sensors should not protrude into the pivoting area of the movable flap, since this can lead to collisions with the object to be detected. Unless the corresponding sensor is used to make the moving part follow the object, as previously described.
Ferner kann es vorgesehen sein, dass die Sensoreinrichtung mit wenigstens einem Sensor zunächst eine Referenzmessung durchführt, um somit Störeinflüsse, wie Witterung, Hindernisse oder dergleichen zunächst zu erfassen. Dieser Referenzmesswert kann in der Elektrikeinheit, insbesondere in der Steuereinheit, als Referenzwert gespeichert werden. Nachdem die Referenzmessung durchgeführt worden ist, kann dann der Sensor eine Detektion eines Objektes in dem Detektionsbereich messtechnisch erfassen. Auf diese Art und Weise können Fehlfunktionen bei der Betätigung des beweglichen Teils zuverlässig vermieden werden. So ist es z. B. denkbar, dass die Sensoreinrichtung bei oder kurz nachdem Parkvorgang die erwähnte Referenzmessung durchführt, um beispielsweise Gegenstände im Detektionsbereich zu erfassen, die später bei einer gewünschten Betätigung der beweglichen Klappe zu Messfehler führen könnten. Auch kann diese Referenzmessung zur Festlegung von Schwellwerten bei der anschließenden Messung genutzt werden. Es sei an dieser Stelle erwähnt, dass es optional möglich ist, die Sensoreinrichtung über einen zusätzlichen Schalter im Fahrzeug ein- bzw. auszuschalten. Auch kann die Aktivierung der Sensoreinrichtung von der fahrzeugseitigen Elektronik gesteuert werden, z. B. über das Lenkradschloss oder den Anlassschalter oder einem Schalter am Ganghebel oder dergleichen.Furthermore, it can be provided that the sensor device initially carries out a reference measurement with at least one sensor in order to initially detect interfering influences such as weather, obstacles or the like. This reference measured value can be stored as a reference value in the electrical unit, in particular in the control unit. After the reference measurement has been carried out, the sensor can then record a detection of an object in the detection area by measurement. In this way, malfunctions in the operation of the movable part can be reliably avoided. So it is e.g. B. conceivable that the sensor device carries out the mentioned reference measurement during or shortly after the parking process, for example to detect objects in the detection area, which could later lead to measurement errors when the movable flap is actuated as desired. This reference measurement can also be used to establish threshold values in the subsequent measurement. It should be mentioned at this point that it is optionally possible to switch the sensor device on or off via an additional switch in the vehicle. The activation of the sensor device can also be controlled by the vehicle electronics, e.g. B. via the steering lock or the starter switch or a switch on the gear lever or the like.
Ebenfalls ist es möglich, dass zumindest ein Sensor oder alle Sensoren der Sensoreinrichtung auf fehlerhafte Steckverbindungen, Lötverbindungen oder Leitungsbrüche hin überwacht werden. Zu diesem Zweck kann z. B. ein Sensor mit einem Endwiderstand ausgestattet sein, der am Ende der Sensorelektrode angeordnet ist. Durch eine Vergleichmessung kann somit festgestellt werden, ob der Widerstand messtechnisch noch erreichbar ist oder nicht. Wird hierbei der Endwiderstand nicht mehr detektiert, so ist davon auszugehen, dass an irgendeiner Stelle ein Defekt bzw. Bruch des Sensors vorliegt, der z. B. als Fehler von dem Steuergerät erfasst und weiter an die Kraftfahrzeugelektronik gemeldet werden kann.It is also possible that at least one sensor or all sensors of the sensor device are monitored for faulty plug connections, soldered connections or line breaks. For this purpose z. B. a sensor can be equipped with a terminal resistor which is arranged at the end of the sensor electrode. A comparison measurement can thus be used to determine whether the resistance can still be achieved in terms of measurement technology or not. If the terminal resistance is no longer detected, it can be assumed that there is a defect or break in the sensor at some point. B. detected as an error by the control unit and can be further reported to the motor vehicle electronics.
Auch ist es denkbar, dass zumindest ein Sensor als durchgehender Leiter ausgestaltet ist und somit kein abschließendes Ende aufweist, wobei dann der Gesamtwiderstand des Sensors eindeutig messtechnisch erfassbar ist. Überschreitet dieser Gesamtwiderstand des Sensors ein vorgegebenen Widerstandswert, so ist hierdurch eindeutig auf einen elektrischen Defekt des Sensors zu schließen. Um trotzdem zu vermeiden, dass der entsprechende Sensor an zwei unterschiedlichen Stellen leitungstechnisch verbunden werden muss, kann das Sensorelement schlaufenförmig oder U-förmig ausgestaltet sein, so dass der Eingangsanschluss und der Ausgangsanschluss des Sensorelementes nebeneinander angeordnet werden kann.It is also conceivable that at least one sensor is designed as a continuous conductor and thus does not have a terminating end, the total resistance of the sensor then being clearly detectable by measurement. If this total resistance of the sensor exceeds a specified resistance value, this clearly indicates an electrical defect in the sensor. In order to avoid that the corresponding sensor has to be wired at two different points, the sensor element can be loop-shaped or U-shaped so that the input connection and the output connection of the sensor element can be arranged next to one another.
Auch ist es denkbar, dass zumindest ein Sensor mit einem Abschirmelement ausgestattet ist. Dieses Abschirmelement kann als Abschirmfolie um den Sensor teilweise gewickelt werden, um somit den Detektionsbereich des Sensors genauer zu definieren. An den Freistellen des Sensors, die nicht von der Abschirmfolie umhüllt bzw. verdeckt sind, ist dann der Detektionsbereich des Sensors geometrisch vorgegeben. So kann beispielsweise ein über die komplette Breite eines Kraftfahrzeuges ausgestalteter Sensor durch das Abschirmelement nur auf die Eckbereiche des Kraftfahrzeuges (Übergang von Heckbereich zum Seitenbereich) gerichtet werden. Zusätzlich ist es denkbar, dass zu einem oder jedem Sensor ein sogenanntes Active-Shield zum Einsatz kommt, um den Detektionsbereich vom Active-Shield weg nach vorne zu richten. Somit ist der jeweilige Sensor zwischen seinem Detektionsbereich und seinem Active-Shield angeordnet. Der jeweilige Sensor kann mit dem Abschirmelement und/oder dem Active-Shield teilweise oder ganz kunststoff- oder gummiumhüllt sein. Die Umhüllung des Sensors kann beispielsweise durch ein Spritz- oder Stranggussverfahren erfolgen. Somit bildet der entsprechende Sensor mit seinem Abschirmelement und/oder seinem Active-Shield ein unzertrennbares Bauteil. Ebenfalls kann auch der Sensor separat zu seinem Abschirmelement und/oder seinem Active-Shield angeordnet werden.It is also conceivable that at least one sensor is equipped with a shielding element. This shielding element can be partially wrapped around the sensor as a shielding film in order to define the detection area of the sensor more precisely. The detection area of the sensor is then geometrically predetermined at the exposed areas of the sensor that are not enveloped or covered by the shielding film. For example, a sensor designed over the entire width of a motor vehicle can only be aimed at the corner areas of the motor vehicle (transition from the rear area to the side area) through the shielding element. In addition, it is conceivable that a so-called active shield is used for one or each sensor in order to direct the detection area forward away from the active shield. The respective sensor is thus arranged between its detection area and its active shield. The respective sensor can be partially or entirely plastic or rubber encased with the shielding element and / or the active shield. The enclosure of the sensor can for example by a spray or Continuous casting process take place. Thus, the corresponding sensor with its shielding element and / or its active shield forms an inseparable component. The sensor can also be arranged separately from its shielding element and / or its active shield.
Der Sensor kann ebenfalls durch eine Matte oder ein Netz direkt oder indirekt an dem Fahrzeug oder dem Trägerteil der Moduleinheit befestigt werden, wobei der Sensor in der Matte oder dem Netz ganz oder teilweise angebettet ist. Die Matte oder das Netz kann dann wiederum indirekt über weitere Haltelemente, insbesondere Rastelemente oder Klipse - wie beschrieben - befestigt werden. Im Bereich der Klipse kann eine zusätzliche Anbindung erfolgen zur verbesserten Sensierung.The sensor can also be attached directly or indirectly to the vehicle or the carrier part of the module unit by a mat or a net, the sensor being completely or partially embedded in the mat or the net. The mat or the net can then in turn be fastened indirectly via further holding elements, in particular locking elements or clips, as described. An additional connection can be made in the area of the clips for improved sensing.
Ebenfalls ist es denkbar, dass bei der erfindungsgemäßen Sensoreinrichtung ein erster Sensor mit einem ersten horizontalen Detektionsbereich und wenigstens ein zweiter Sensor mit einem zweiten vertikalen Detektionsbereich am Kraftfahrzeug vorgesehen ist, um somit nicht nur den Eintritt des Objektes in den Detektionsbereich eines Sensors zu erfassen, sondern auch die entsprechende Bewegung des Objektes. Durch den Einsatz von mindestens zwei Sensoren der erfindungsgemäßen Sensoreinrichtung können auch zwei aufeinander folgende unterschiedliche Richtungen des Objektes in den jeweiligen Detektionsbereichen festgestellt werden.It is also conceivable that, in the sensor device according to the invention, a first sensor with a first horizontal detection area and at least one second sensor with a second vertical detection area are provided on the motor vehicle in order not only to detect the entry of the object into the detection area of a sensor, but also also the corresponding movement of the object. By using at least two sensors of the sensor device according to the invention, two different directions of the object following one another can also be determined in the respective detection areas.
Um zusätzlich die Messgenauigkeit oder Messmöglichkeiten der Sensoreinrichtungen zu verbessern, kann es vorgesehen sein, dass zumindest eine kapazitive Kopplung eines Sensors veränderbar ist. Ebenfalls ist es denkbar, dass auch die kapazitive Kopplung der weiteren Sensoren veränderbar ausgestaltet ist oder diese erst nach einer Änderung eines ersten Sensors erfolgt. Hierbei kann auch die kapazitive Änderung über einen Schwellwert geregelt werden, so dass z. B. der erste Sensor zwar auslöst aber der zweite Sensor erkennt, dass bereits das Objekt in seinem Detektionsbereich eingetreten ist aber noch nicht vollständig darin vorhanden ist. Somit kann die Betätigung des beweglichen Teils auch gezielt über einen nur teilweisen Eintritt des Objektes in den Detektionsbereich eines Sensors gesteuert werden.In order to additionally improve the measuring accuracy or measuring possibilities of the sensor devices, it can be provided that at least one capacitive coupling of a sensor can be changed. It is also conceivable that the capacitive coupling of the further sensors is also designed to be changeable or that this takes place only after a first sensor has been changed. Here, the capacitive change can also be regulated via a threshold value, so that, for. B. the first sensor triggers but the second sensor detects that the object has already entered its detection area but is not yet completely present in it. The actuation of the movable part can thus also be controlled in a targeted manner via only partial entry of the object into the detection area of a sensor.
Es sei an dieser Stelle erwähnt, dass z. B. ein Zugangsberechtigungssystem und/oder ein Sicherheitssystem erst dann angesteuert wird, wenn zumindest ein Sensor der Sensoreinrichtung ein Objekt in seinem Detektionsbereich wahrnimmt. Ebenfalls kann die Ansteuerung des Zugangsberechtigungssystems oder des Sicherheitssystems erst dann erfolgen, wenn sichergestellt wird, dass dieses Objekt tatsächlich ein Zugang zum Fahrzeug wünscht. Dieses kann beispielsweise über die erfolgreiche Erfassung eines Bewegungsablaufes des Objektes stattfinden oder in dem zwei oder mehrere Sensoren das Objekt im Detektionsbereich erfassen. Somit ist es auch denkbar, dass die Ansteuerung des Zugangsberechtigungssystems und/oder des Sicherheitssystems erst dann erfolgt, wenn der Messwert eines Sensors unter einem vorgegebenen Schwellwert fällt bzw. fallen wird.It should be mentioned at this point that z. B. an access authorization system and / or a security system is only activated when at least one sensor of the sensor device perceives an object in its detection area. The access authorization system or the security system can also only be activated when it is ensured that this object actually wants access to the vehicle. This can take place, for example, via the successful detection of a movement sequence of the object or in which two or more sensors detect the object in the detection area. It is therefore also conceivable that the access authorization system and / or the security system are only activated when the measured value of a sensor falls or will fall below a predetermined threshold value.
Üblicherweise wird der Zugang zum Fahrzeug erst dann freigegeben, wenn das Zugangsberechtigungssystem und/oder das Sicherheitssystem mit einem mobilen ID-Geber eine erfolgreiche Sicherheitsabfrage zum Zugangscode durchgeführt hat. Genau diese Abfrage kann jedoch von dem Messergebnis der erfindungsgemäßen Sensoreinrichtung abhängig gemacht werden, wie zuvor beschrieben.Access to the vehicle is usually only released when the access authorization system and / or the security system with a mobile ID transmitter has carried out a successful security query for the access code. However, precisely this query can be made dependent on the measurement result of the sensor device according to the invention, as described above.
Ebenfalls ist es vorstellbar, dass zumindest ein Sensor der erfindungsgemäßen Sensoreinrichtung als Antenne oder als zusätzliche Antenne für das Zugangsberechtigungssystem und/oder das Sicherheitssystem dient. Die Abfrage des Zugangsberechtigungssystems, beispielsweise über den mobilen ID-Geber oder eine Keyless-Go-Card, kann muss aber jedoch nicht dazu dienen, die erfindungsgemäße Sensoreinrichtung zu aktivieren. Vielmehr kann auch die Sensoreinrichtung dazu dienen, das Zugangsberechtigungssystem und/oder das Sicherheitssystem aufzuwecken. Die zusätzliche Abfrage des ID-Gebers stellt lediglich eine weitere Verbesserung der Sicherheit dar, um ein unberechtigtes Öffnen des beweglichen Teils am Kraftfahrzeug zu verhindern.It is also conceivable that at least one sensor of the sensor device according to the invention serves as an antenna or as an additional antenna for the access authorization system and / or the security system. The query of the access authorization system, for example via the mobile ID transmitter or a keyless go card, however, does not have to serve to activate the sensor device according to the invention. Rather, the sensor device can also serve to wake up the access authorization system and / or the security system. The additional query of the ID transmitter merely represents a further improvement in security in order to prevent unauthorized opening of the movable part on the motor vehicle.
Es sei der vollständigkeitshalber noch erwähnt, dass die Detektion eines Objektes sowohl bei einem verriegelten Kraftfahrzeug als auch bei einem geöffneten Kraftfahrzeug erfolgen kann.For the sake of completeness, it should also be mentioned that the detection of an object can take place both when the motor vehicle is locked and when the motor vehicle is open.
Ebenfalls kann über die Sensoreinrichtung eine Betätigung der Kameravorrichtung, insbesondere der Heckkameravorrichtung gesteuert bzw. aktiviert werden, um beispielsweise mechanische Kollisionen des Fahrzeuges oder auch nur des beweglichen Teils beim Öffnungsvorgang mit einer Umgebung zu vermeiden. Ebenfalls ist es denkbar, dass auch andere technische Mittel zur zuvor genannten Kamera vorgesehen sind, um eine Kollision des beweglichen Teils beim Öffnen oder Schließen mit einem Hindernis oder Gegenstand zu verhindern. Hierbei kann es sich beispielsweise auch um einen weiteren Näherungssensor, ein Radarsystem oder einen Ultraschallsensor oder dergleichen handeln. Somit ist sichergestellt, dass der Öffnungs- oder Schließvorgang des beweglichen Teils - beispielsweise erst nach einer möglichen Authentifikation - erfolgt, wenn sichergestellt ist, dass kein Gegenstand oder Hindernis im Bewegungsbereich des beweglichen Teils vorhanden ist. Dieses kann insbesondere bei niedrigen Garagen von besonderer Bedeutung sein. Auch kann die erfindungsgemäße Sensoreinrichtung zur Erfassung von Bodenvertiefungen- und erhöhungen im Detektionsbereich seiner Sensoren dienen, um Kollisionen des Fahrzeuges zu vermeiden. Die Messergebnisse der Sensoren können z. B. als Warnhinweise im Kraftfahrzeug an die Insassen ausgegeben werden.An actuation of the camera device, in particular the rear camera device, can also be controlled or activated via the sensor device For example, to avoid mechanical collisions of the vehicle or even only the moving part with an environment during the opening process. It is also conceivable that other technical means for the aforementioned camera are also provided in order to prevent the movable part from colliding with an obstacle or object when it is opened or closed. This can also be, for example, a further proximity sensor, a radar system or an ultrasonic sensor or the like. This ensures that the opening or closing process of the movable part takes place - for example only after possible authentication - when it is ensured that there is no object or obstacle in the movement area of the movable part. This can be particularly important in low garages. The sensor device according to the invention can also be used to detect depressions and elevations in the detection area of its sensors in order to avoid collisions of the vehicle. The measurement results of the sensors can e.g. B. issued as warnings in the vehicle to the occupants.
Auch ist es denkbar, dass zumindest ein Sensor der Sensoreinrichtung genutzt wird, um festzustellen, ob sich ein Objekt, insbesondere eine Person im Bewegungsbereich des beweglichen Teils befindet. Erst wenn durch den Sensor sichergestellt ist, dass kein Objekt erfasst wird, kann somit die Ansteuerung des beweglichen Teils durch die Elektronikeinheit, insbesondere Steuereinheit, freigegeben werden, um das bewegliche Teil zu betätigen. Hierbei kann die Einklemmgefahr wirkungsvoll reduziert werden. Selbstverständlich können dazu auch die weiteren fahrzeuginternen Sensorsysteme, wie z.B. das Parksystem, das Abstandswarnsystem oder dergleichen genutzt werden, um festzustellen, dass eine gefährdete Person außerhalb des Gefahrenbereichs des beweglichen Teils vorhanden ist.It is also conceivable that at least one sensor of the sensor device is used to determine whether an object, in particular a person, is located in the range of motion of the movable part. Only when the sensor ensures that no object is detected can the control of the movable part by the electronics unit, in particular the control unit, be released in order to operate the movable part. The risk of trapping can be effectively reduced here. Of course, the other vehicle-internal sensor systems, such as the parking system, the distance warning system or the like, can also be used to determine that a person at risk is outside the danger area of the moving part.
Ferner ist es denkbar, dass ein Sensor der Sensoreinrichtung mittels Halteelementen an dem Fahrzeug, insbesondere an der Innenseite des Stoßfängers oder des beweglichen Teils bzw. am Türschwellerbereich, angeordnet sein. Die Halteelemente können selbst als Klipse oder Rastelemente ausgestaltet sein. Die Klipse selbst können ebenfalls anklebbar ausgestaltet sein, um z. B. den Sensor stoffschlüssig zu halten. Auch können formschlüssige Schlaufen oder Haltemittel an den Klipsen zur Befestigung des Sensors vorgesehen sein. Grundsätzlich kann zumindest ein Sensor über den Trägerkörper zu der erfindungsgemäßen Moduleinheit verbunden werden. Ebenfalls ist es denkbar, dass für jeden Sensor ein gesonderter Trägerkörper vorhanden ist, um die Moduleinheit zu bilden. Selbstverständlich können auch an einem Trägerkörper mehrere Sensoren nebeneinander, parallel oder hintereinander angeordnet sein. Auch ist es denkbar, dass zumindest ein Sensorelement außerhalb der Moduleinheit angeordnet ist, wobei hingegen ein anderer Sensor an dem Trägerelement der Moduleinheit vorgesehen ist.Furthermore, it is conceivable that a sensor of the sensor device can be arranged on the vehicle, in particular on the inside of the bumper or the movable part or on the door sill area, by means of holding elements. The holding elements can themselves be designed as clips or locking elements. The clips themselves can also be designed so that they can be glued to, for. B. to hold the sensor cohesively. Form-fitting loops or retaining means can also be provided on the clips for fastening the sensor. In principle, at least one sensor can be connected to the module unit according to the invention via the carrier body. It is also conceivable that a separate carrier body is present for each sensor in order to form the module unit. Of course, several sensors can also be arranged next to one another, parallel or one behind the other on a carrier body. It is also conceivable that at least one sensor element is arranged outside of the module unit, whereas another sensor is provided on the carrier element of the module unit.
Grundsätzlich kann zumindest ein Sensor mäanderförmig oder schlaufen- bzw. schleifenförmig angeordnet sein, um sein Detektionsbereich zu bilden. Diese Ausgestaltung des Sensors ist insbesondere dann von besonderer Bedeutung, wenn der Sensor nicht nur erfassen soll, ob ein Objekt vollständig im Detektionsbereich ist oder nicht, sondern wenn der Sensor auch erfassen soll, ob das Objekt ganz oder teilweise in seinem Detektionsbereich eingedrungen ist. Somit eignet sich diese Ausgestaltung des Sensors insbesondere dann, wenn mit Schwellwerten bei der Messung gearbeitet wird. Selbstverständlich können auch mehrere Sensoren der erfindungsgemäßen Sensoreinrichtung derart ausgestaltet sein.In principle, at least one sensor can be arranged in a meander shape or in a loop or loop shape in order to form its detection area. This configuration of the sensor is particularly important if the sensor should not only detect whether an object is completely in the detection area or not, but if the sensor should also detect whether the object has penetrated its detection area entirely or partially. This configuration of the sensor is therefore particularly suitable when working with threshold values in the measurement. Of course, several sensors of the sensor device according to the invention can also be designed in this way.
Auch ist es denkbar, dass die erfindungsgemäße Sensoreinrichtung zusätzlich ein Einparksystem oder ein Fahrleitsystem unterstützt bzw. sogar bei kurzen Distanzen, d. h. unter 2 m vollständig ersetzt. Die an der erfindungsgemäßen Sensoreinrichtung erfassten Messsignale können somit auch dazu genutzt werden, um die Fahrsicherheit des Kraftfahrzeuges, insbesondere beim Einparken oder bei niedrigsten Geschwindigkeiten, zu unterstützen.It is also conceivable that the sensor device according to the invention additionally supports a parking system or a driving guidance system or even for short distances, i.e. H. completely replaced under 2 m. The measurement signals detected at the sensor device according to the invention can thus also be used to support the driving safety of the motor vehicle, in particular when parking or at the lowest speeds.
Ebenfalls ist es denkbar, dass ein Sensor zusätzlich mit einem Heizelement ausgestattet ist bzw. ein entsprechendes Heizelement in der Nähe eines Sensors angeordnet ist, um möglichst Wasser im Bereich des Sensors durch zusätzliche Wärmeeinwirkung schnellstmöglich verdunsten zu lassen. Auch kann dieses Heizelement zum Auftauen von gefrorenem Wasser dienen, was sich am Sensor oder in unmittelbarer Nähe festgefroren hat. Hierdurch lässt sich die Messgenauigkeit deutlich erhöhen, da gerade Wasser bei einem kapazitiven Sensor für große messtechnische Störeinflüsse sorgt. Dabei ist es auch denkbar, dass das Heizelement je nach Witterung temporär durch die Elektrikeinheit ein- und ausgeschaltet wird, um somit regelmäßig dafür zu sorgen, dass die direkte Umgebung des jeweiligen Sensors wasserfrei ausgestaltet ist. Es sei auch erwähnt, dass es denkbar ist, den Sensor selbst oder z. B. ein Abschirmelement für den Sensor als Heizelement zu verwenden. Hierfür kann die Steuereinheit sorgen, in dem sie beispielsweise den Sensor oder das Abschirmelement entsprechend einmal als Heizelement anschaltet und einmal als Sensor oder Abschirmelement nutzt. Selbstverständlich kann auch ein zusätzliches Heizelement vorhanden sein, um die erforderliche Wärme zu erzeugen. Nur der Vollständigkeit halber sei erwähnt, dass das Heizelement mit dem Sensor und ggf. dem Abschirmelement zu einem Bauteil durch z. B. eine Umhüllung oder eine Isolierung zusammengefasst sein kann.It is also conceivable that a sensor is additionally equipped with a heating element or a corresponding heating element is arranged in the vicinity of a sensor in order to allow water to evaporate as quickly as possible in the area of the sensor through the action of additional heat. This heating element can also be used to thaw frozen water that has frozen onto the sensor or in the immediate vicinity. This allows the measurement accuracy to be increased significantly, since water in particular causes great metrological interference with a capacitive sensor. It is also conceivable that the heating element is temporarily switched on and off by the electrical unit, depending on the weather is switched off in order to regularly ensure that the direct environment of the respective sensor is designed to be water-free. It should also be mentioned that it is conceivable to use the sensor itself or e.g. B. to use a shielding element for the sensor as a heating element. The control unit can ensure this by switching on the sensor or the shielding element once as a heating element and using it once as a sensor or shielding element. Of course, an additional heating element can also be present in order to generate the required heat. For the sake of completeness, it should be mentioned that the heating element with the sensor and possibly the shielding element to a component by z. B. an envelope or insulation can be combined.
Zweckmäßigerweise sind zusätzlich Wasserleitelemente entweder direkt an dem Sensor, dem Trägerkörper für die Moduleinheit oder dem Stoßfänger, dem Türschweller oder dergleichen angeordnet, mit deren Hilfe versucht wird, vorhandenes Wasser möglichst aus dem Detektionsbereich des entsprechenden Sensors abzuleiten. Hierdurch sollen die bereits zuvor beschriebenen Störungen bzw. negativen Messeinflüsse auf den jeweiligen Sensor durch das ggf. vorhandene Wasser weitestgehend minimiert werden. Die Wasserleitelemente können selbst als Vorsprünge oder Abrisskanten oder als Entwässerungsrinnen bzw. Löcher ausgestaltet sein. Es soll somit verhindert werden, dass sich ein Wasserfilm, insbesondere im direkten Detektionsbereich des Sensors bildet. Die Wasserleitelemente können z.B. keilförmig ausgestaltet sein, wodurch sich eine Abrisskante für einen Wasserlauf bildet, an dem sich dann die Wassertropfen von dem Wasserleitelement trennen. Auch kann das Wasserleitelement nur aus einer Abrisskante bestehen, die in dem Trägerkörper oder dem Stoßfänger oder dergleichen eingearbeitet ist. Auch sind Wasserrinnen oder Durchbrüche zum Ableiten bzw. Wegleiten des Wassers vom Sensor denkbar, die am Trägerkörper oder dem Fahrzeug, insbesondere dem Stoßfänger, dem Türschweller oder dergleichen angeordnet sind.In addition, water guide elements are expediently arranged either directly on the sensor, the support body for the module unit or the bumper, the door sill or the like, with the help of which an attempt is made to divert existing water as far as possible from the detection area of the corresponding sensor. This is intended to minimize the previously described disturbances or negative measuring influences on the respective sensor due to the water that may be present. The water guide elements themselves can be designed as projections or tear-off edges or as drainage channels or holes. The aim is to prevent a film of water from forming, in particular in the direct detection area of the sensor. The water guide elements can, for example, be designed in a wedge shape, whereby a tear-off edge is formed for a watercourse, on which the water droplets then separate from the water guide element. The water guide element can also consist only of a tear-off edge which is incorporated into the carrier body or the bumper or the like. Also conceivable are gutters or breakthroughs for diverting or guiding the water away from the sensor, which are arranged on the support body or the vehicle, in particular the bumper, the door sill or the like.
Die Erfindung wird ebenfalls durch ein Verfahren mit allen Merkmalen des Anspruches 35 gelöst. Weitere mögliche Ausführungsformen des Verfahrens sind in den jeweiligen Verfahrensunteransprüchen vorgeschlagen.The invention is also achieved by a method having all of the features of
Beispielsweise ist es denkbar, dass ein erster und ein zweiter Sensor vorgesehen ist, wobei das Objekt, insbesondere der berechtigte Benutzer, eine bewusste Handlung vornimmt, die vom ersten oder zweiten Sensor erfasst wird. Die bewusste Handlung kann beispielsweise eine Annäherung des Benutzers mit seinem Arm oder Hand in die Nähe des erste oder des zweiten Sensors sein. Selbstverständlich ist es ebenfalls möglich, dass die Moduleinheit lediglich mit einem Sensor zur entsprechenden Detektion eines Objektes auskommt, wodurch über die Detektion die Betätigung des beweglichen Teils aktivierbar ist.For example, it is conceivable that a first and a second sensor are provided, the object, in particular the authorized user, performing a conscious action that is detected by the first or second sensor. The conscious action can be, for example, bringing the user closer to the first or the second sensor with his arm or hand. Of course, it is also possible that the module unit only needs one sensor for the corresponding detection of an object, whereby the actuation of the movable part can be activated via the detection.
Beispielsweise ist es in einer möglichen Ausführungsform der Erfindung denkbar, dass zur Detektion zuerst der erste und anschließend der zweite Sensor aktiviert werden oder dass zur Detektion beide Sensoren gleichzeitig aktiviert werden.For example, in a possible embodiment of the invention, it is conceivable that for detection first the first and then the second sensor are activated or that both sensors are activated simultaneously for detection.
In einer weiteren Alternative wird eine bewußte Bein- oder Fußbewegung des Benutzers durch den ersten Sensor detektiert und eine weitere Körperbewegung des Benutzers durch den zweiten Sensor detektiert.In a further alternative, a conscious leg or foot movement of the user is detected by the first sensor and a further body movement of the user is detected by the second sensor.
Ferner kann vorgesehen sein, dass während der Detektion mindestens eine Leuchteinheit des Kraftfahrzeuges eine definierte Leuchtweise aufweist.Furthermore, it can be provided that at least one lighting unit of the motor vehicle has a defined lighting mode during the detection.
In einer möglichen Ausführungsform der Erfindung ist die Moduleinheit am Heckbereich und/oder am Seitentürbereich des Kraftfahrzeuges insbesondere unterhalb einer Seitenschiebetür angeordnet ist. Über eine entsprechende Detektion einer Person, die sich in der Nähe der Seitenschiebetür des Kraftfahrzeuges befindet, kann ein Öffnungsvorgang der Schiebetür ausgelöst werden. Diese Ausführungsform ist gerade bei Fahrzeugen, die als Nutzfahrzeuge, insbesondere als Transporter oder Kleintransporter, ausgeführt sind, nützlich.In one possible embodiment of the invention, the module unit is arranged on the rear area and / or on the side door area of the motor vehicle, in particular below a sliding side door. An opening process of the sliding door can be triggered by a corresponding detection of a person who is in the vicinity of the sliding side door of the motor vehicle. This embodiment is particularly useful in vehicles that are designed as utility vehicles, in particular as transporters or small transporters.
Vorteilhafterweise ist die Elektrikeinheit mit mindestens einem dritten Sensoren und/oder Schalter verbunden ist, der innerhalb des Kraftfahrzeuges angeordnet ist, insbesondere dass der dritte Sensor und/oder Schalter derart im Kraffahrzeug angeordnet ist, dass er über den Fuß, und/oder Knie und/oder und/oder Ellenbogen und/oder Schulter und/oder Kopf des Benutzers betätigbar ist. Ferner ist es denkbar, dass durch eine Betätigung des dritten Sensors oder/oder Schalters eine Öffnungsbewegung und/oder Schließbewegung der Seitenschiebetür auslösbar ist. Falls der Benutzer sich innerhalb des Kraftfahrzeuges befindet, ist über die Betätigung des dritten Sensors und/oder Schalters ein Schließen der Schiebtür des Kraftfahrzeuges denkbar. Ein erneutes Öffnen der Seitenschiebetür durch Betätigung des dritten Sensors und/oder Schalters kann ebenfalls ausgelöst werden. Der dritte Sensor und/oder Schalter kann als Näherungssensor, berührungsloser Sensor oder als taktiler Druckschalter ausgeführt sein.The electrical unit is advantageously connected to at least one third sensor and / or switch that is arranged inside the motor vehicle, in particular that the third sensor and / or switch is arranged in the motor vehicle in such a way that it is placed over the foot and / or knee and / or or and / or elbow and / or shoulder and / or head of the user can be actuated. Furthermore, it is conceivable that by actuating the third sensor or / or switch, an opening movement and / or closing movement of the Side sliding door is triggered. If the user is inside the motor vehicle, it is conceivable to close the sliding door of the motor vehicle by actuating the third sensor and / or switch. A renewed opening of the sliding side door by actuating the third sensor and / or switch can also be triggered. The third sensor and / or switch can be designed as a proximity sensor, non-contact sensor or as a tactile pressure switch.
Vorteilhafterweise ist der dritte Sensor und/oder Schalter zur Auslösung einer Öffnungsbewegung und/oder Schließbewegung der Seitenschiebetür des Kraftfahrzeuges in oder an der Seitenschiebetür angeordnet. Ebenfalls ist eine Anordnung in oder an der Türverkleidung, am Fahrzeugsitz oder im Bodenbereich oder an diversen Zierelementen innerhalb des Kraftfahrzeuges denkbar.The third sensor and / or switch for triggering an opening movement and / or closing movement of the sliding side door of the motor vehicle is advantageously arranged in or on the sliding side door. An arrangement in or on the door trim, on the vehicle seat or in the floor area or on various decorative elements within the motor vehicle is also conceivable.
In einer möglichen Ausführungsform kann eine Schließbewegung der Seitenschiebetür dadurch ausgelöst werden, dass der Benutzer beispielsweise den innenliegenden dritten Sensor und/oder Schalter aktiviert. Ebenfalls ist es denkbar, dass beim Verlassen des Kraftfahrzeugs der Benutzer zunächst den innenliegenden dritten Sensor und/oder Schalter betätigen muss. Anschließend ist eine weitere Detektion des Sensors der Moduleinheit notwendig, um einen tatsächlichen Schließvorgang der Seitenschiebetür auszulösen. Ferner ist es ebenfalls denkbar, dass eine Auslösung des innenliegenden dritten Sensors über ein definiertes Bewegungsmuster realisierbar ist.In one possible embodiment, a closing movement of the sliding side door can be triggered by the user activating the third sensor and / or switch located on the inside, for example. It is also conceivable that, when leaving the motor vehicle, the user must first actuate the third sensor and / or switch located inside. Another detection of the sensor of the module unit is then necessary in order to trigger an actual closing process of the sliding side door. Furthermore, it is also conceivable that the internal third sensor can be triggered via a defined movement pattern.
Zweckmäßigerweise ist der dritte Sensor in Abhängigkeit vom Betriebszustand des Kraftfahrzeuges deaktivierbar. Das bedeutet, dass beim "laufenden" bzw. aktivierten Motor der dritte Sensor und/oder Schalter zur Öffnung der Seitenschiebetür deaktiviert ist. Dennoch kann vorgesehen sein, dass eine derartige Deaktivierung durch den Benutzer wiederum deaktiviert werden kann, damit auch beim "laufenden" Motor der Benutzer über den dritten Sensor und/oder Schalter eine Schließbewegung und/oder Öffnungsbewegung der Seitenschiebtür auslösen kann.The third sensor can expediently be deactivated as a function of the operating state of the motor vehicle. This means that when the motor is "running" or activated, the third sensor and / or switch for opening the sliding side door is deactivated. Nevertheless, it can be provided that such a deactivation can in turn be deactivated by the user so that the user can initiate a closing movement and / or opening movement of the sliding side door via the third sensor and / or switch even when the motor is "running".
Ebenfalls kann vorgesehen sein, dass über eine Betätigung des dritten Sensors eine Entriegelung und/oder Verriegelung einer weiteren Kraftfahrzeugtür und/oder Heckklappe und/oder Tankklappe auslösbar ist.It can also be provided that an unlocking and / or locking of a further motor vehicle door and / or tailgate and / or fuel filler flap can be triggered by actuating the third sensor.
Darüber hinaus ist es möglich, dass die Geschwindigkeit der Öffnungsbewegung und/oder Schließbewegung der Schiebetür veränderbar ist, insbesondere die Elektrikeinheit die Geschwindigkeit der Öffnungsbewegung und/oder Schließbewegung der Schiebetür steuert und/oder regelt.In addition, it is possible that the speed of the opening movement and / or closing movement of the sliding door can be changed, in particular the electrical unit controls and / or regulates the speed of the opening movement and / or closing movement of the sliding door.
Das erfindungsgemäße Verfahren kann derart ausgestaltet sein, dass die tatsächliche Aktivierung des beweglichen Teils nach einer definierten Zeit und/oder in Abhängigkeit von einem definierten Abstand erfolgt, den der Benutzer zur Moduleinheit aufweisen muss. Hierbei kann vorgesehen sein, dass eine definierte Zeit vorgegeben ist, die zeitversetzt nach einer positiven Detektion und/oder nach einem positiven Authentifizierungsvorgang die Öffnung des beweglichen Teils auslöst. Ebenfalls kann es aufgrund der Konstruktion des Kraftfahrzeuges, insbesondere des beweglichen Teils, von Vorteil sein, dass eine Öffnung des beweglichen Teils erst dann erfolgt, wenn sich der Benutzer in einem definierten Abstand zum beweglichen Teil befindet. Das bedeutet, dass über die erfindungsgemäße Sensoreinrichtung, die sich in der Moduleinheit sich befindet, der notwendige Abstand zum Benutzer ermittelt wird. In einer möglichen Ausführungsform kann es notwendig sein, dass der Benutzer sich erst vom beweglichen Teil wegbewegen muss, damit eine Betätigung des beweglichen Teils ausgelöst wird.The method according to the invention can be designed in such a way that the actual activation of the movable part takes place after a defined time and / or as a function of a defined distance that the user must have from the module unit. It can be provided here that a defined time is specified which triggers the opening of the movable part with a time delay after a positive detection and / or after a positive authentication process. Due to the construction of the motor vehicle, in particular of the movable part, it can also be advantageous that the movable part is only opened when the user is at a defined distance from the movable part. This means that the necessary distance from the user is determined via the sensor device according to the invention, which is located in the module unit. In one possible embodiment, it may be necessary for the user to first move away from the movable part so that an actuation of the movable part is triggered.
Ebenfalls kann vorgesehen sein, dass die Moduleinheit mit einer eigenen Leuchteinheit ausgeführt ist, die entsprechend ihrer Leuchtweise den notwendigen Abstand dem Benutzer kommuniziert. Falls sich der Benutzer noch zu Nahe am Kraftfahrzeug befindet, kann beispielsweise die Leuchteinheit mit einer ersten Farbe dem Benutzer eine entsprechende Information signalisieren. Befindet sich der Benutzer in einer ausreichenden Entfernung zur Moduleinheit, wechselt die Leuchteinheit ihre Farbe und die Öffnungsbewegung des beweglichen Teils kann erfolgen.It can also be provided that the module unit is designed with its own lighting unit, which communicates the necessary distance to the user according to its lighting mode. If the user is still too close to the motor vehicle, the lighting unit can, for example, use a first color to signal corresponding information to the user. If the user is at a sufficient distance from the module unit, the light unit changes its color and the moving part can be opened.
Ebenfalls kann es vorgesehen sein, dass über einen ID-Geber, den der Benutzer mit sich trägt, der Authentifizierungsvorgang gestartet wird und die Sensoreinrichtung aktiviert wird, obwohl insbesondere der Benutzer sich außerhalb des Detektionsbereiches befindet. Hierbei bietet das erfindungsgemäße Verfahren die Möglichkeit, dass der Benutzer in größerer Entfernung zum Kraftfahrzeug den ID-Geber betätigen kann, sodass zunächst der Authentifizierungsvorgang ausgelöst wird. Erst wenn sich der Benutzer in der Nähe des Kraftfahrzeuges, insbesondere der Moduleinheit, befindet, erfolgt eine entsprechende Detektion über die Sensoreinrichtung, um die Betätigung des beweglichen Teils zu aktivieren. Das bedeutet, dass der Authentifizierungsvorgang vor dem Detektionsvorgang zur Betätigung des beweglichen Teils vorgelagert sein kann. Die Sensoreinrichtung kann nach positiver Authentifikation bereits aktiviert sein.It can also be provided that the authentication process is started and the sensor device is activated via an ID transmitter that the user carries with him, even though the user in particular is outside the detection area. Here, the method according to the invention offers the possibility that the user can operate the ID transmitter at a greater distance from the motor vehicle, so that initially the Authentication process is triggered. Only when the user is in the vicinity of the motor vehicle, in particular the module unit, does a corresponding detection take place via the sensor device in order to activate the actuation of the movable part. This means that the authentication process can precede the detection process for actuating the movable part. The sensor device can already be activated after positive authentication.
Ebenfalls ist es denkbar, dass in Abhängigkeit eines Geschwindigkeitssignals eine Betätigung des beweglichen Teils erfolgt. Das bedeutet, dass lediglich, wenn das Kraftfahrzeug steht und sich nicht bewegt, eine Betätigung des beweglichen Teils möglich ist. In einer weiteren möglichen Alternative ist ein dritter Sensor vorgesehen, wobei über eine positive Detektion über den ersten und den zweiten Sensor die Klappe sich öffnet, über eine positive Detektion über den ersten und den dritten Sensor eine an der Klappe angeordnete Scheibe sich öffnet und über eine positive Detektion über den zweiten und den dritten Sensor die Klappe sich schließt.It is also conceivable that the movable part is actuated as a function of a speed signal. This means that actuation of the movable part is only possible when the motor vehicle is stationary and not moving. In a further possible alternative, a third sensor is provided, the flap opening via a positive detection via the first and the second sensor, a pane arranged on the flap opening via a positive detection via the first and the third sensor and via a positive detection via the second and third sensor, the flap closes.
